Irukandji jellyfish sting two at Cable Beach

The captain of a surf club was one of two people stung by Irukandji jellyfish at Broome's Cable Beach at the weekend.

Cable Beach was closed twice after a 21-year-old woman and a 52-year-old man were stung.

The woman was stung on the arm on Saturday and beach inspector Tim Trew says within 15 minutes she was in severe pain and had trouble breathing.

"She kept saying to us that she felt like she was going to die," he said.

The captain of the Broome Life Saving Club was stung on the left arm yesterday morning.

Volunteer surf lifesaver Catherine Fitzharding says it is still impossible to predict when jellyfish will be at the beach.

" You just never know with these things I guess," she said.

" They're still doing studies into it and we can't really track when they're going to be there or when they're not, so it's best to be on the safe side and that's why we closed the beach as soon as those things happened. "
